IMPROVEMENT IN PLOW-COULTERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it 'may concern-.-

Be it known that I, JOHN LANE, of Chicago, in the county of Cook, and State of Illinois, have invented certain new and useful Improvements in Plows; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever `they occur.

To enable others skilled in the art to construct and use my invention, I'will proceed to describe it.

This invention consists in an improved caster-Coulter for plows, which is adjustable vertically and laterally, and also back and forth along the plow-beam.

Figure l is a side elevation of a portion of a plowbeam with my coulter attached.

Figure 2, an 'end view of the same.

Figure 3 is a horizontal cross-section on the red line of iig. 1.

Figure 4, a face view of one of the pieces.

My coulter consists of a circular steel disk, or Coulter,

A, mounted in the lower', forked end of a stem, or standard, B, the upper portion of which is round, and is provided on one side with a short projecting pin, or lug, a, as shown in fig. 3. l

d I next construct a block, D, of the form shown in figs. 2, 3, 4, which is, with aprojecting portion at the middle, equal in width to the diameter of the casterspindle, and has across it a semicircular groove, so that it will fit to and around the said spindle.

This blockl is also provided with a slot, c, to receive thepin a on the stem, as shown in figs. 3 and 4, the said slot ruiming at right angles to the direction of the semicircular groove in the block, also shownin figs. 3 and 4. Y

This block D, I place against the side of the beam, with .the grooved face outward, and then place the Coulter-stem in it, with the pin a projecting into the slot c, and place over them both a hol-der, or body, C, which body is, in cross-section, Ushaped, and the interior of which is of such size as to admit the stem of the caster, this body fitting over and holding the stem in place against the block, and bearing upon the projecting ends of the block, and holding it in place, asV

shown in fig. 3.

The body C has a portion cnt away on each edge, at

the back, as shown in iig. 2, thus leaving projecting lugs at each end, which serve to prevent the block D from working ont from under the bodyO at thc ends.

On the outside of the body O, and diagonally across it from corner to corner, I form a groove, and also extend it across the ends, and then place over the whole an iron band, or clamp, E, with its arms extending around over the beam, and having a plate, G, provided with a hole in each end, slipped over the ends of the said arms, and nuts placed on them, by means of which the whole apparatus may be held together, and the holder of body O and the block D both securely fastened in place ou the side of the beam, the stem B of' the Coulter being free to turn or oscillate in its bearings, but prevented from moving vertically by the pin a.

The distance between the arms of the clamp E is greater than `the width. of the beam, so that there is always a space between the beam andthe arms, on the lower or upper side, according as the clamp is moved up or down, and greater or less, according to the angle at which the clamp 'st-ands across it: i

To iill this space, and assist in holding theclamp in position, I provide a wedge-shaped block, F, having a series of grooves across it, as shown. This block is inserted under yone of the arms of the clamp, between it and the beam, iii-st placing the clamp so as to stand straight across the beam, and then slipping the block under and swinging' the clamp around, until one ofthe arms rests in one of the grooves in the block, at the thick or thin end, according to the inclination it is desired to give the clamp. This adjustment of the clamp also moves the holder O and block D, and consequently the Coulter itself.

The back of the blockD, the side next the beam, is made rounding, shown in iig. 2, and projects beyond the line of the lugs s on the holder O, so that the holder and block may rock upon the said rounded part, as one or the other arms of the clamp is shortened, by turning up the nut on it, thus throwing the coulter sidewise, in or out from under the plow-beam, as indicated by the dotted red lines in fig. 2.

By loosening the clamp E, so `as to free the block D from the pressure oi' the holder O, the block may be moved up or down it, and thus vary the depth to which the coulter will cut.

It will be seen, that by the above arrangement of parts, provision is made for four different adjustments of the coulter, viz:

First, the vertical adjustment, .by moving the block D up and down between the holder and the beam;

Second, therocking motion of the holder and block, giving a lateral movement to the coulter, as shown in iig. 2;

Third, by changing the angle, or inclination fore and aft; and

Fourth, by moving the whole device along Athe beam,

from one point to another.

Having thus described my invention,

1. Imparting to the coulter A, a lateral adjustment, by making that portion D of its bearing which comes in contact with the beam, rounded, substantially as described.

2. The combination of the holder O and slotted adj nstable. block D, for holding the coulter in position, and adj ust-ing the same vertically, as set forth.

3. The corrugated, or groovcd plate F, in combination with the holder O and staple lil, ior adjusting the Coulter, and adapting it to plows with different-sized struoted and arranged to operate substantially as and beams, substantially as set forth. for the purpose set forth.

4. The holder C, constructed :is described, and bzw- JOHN LANE. ing thedizigonnl groove for the sta-ple, as set. forth. Witnesses:
